This study found it might be possible to implement a Saturn probe mission in which a flyby carrier-relay spacecraft (CRSC) would deliver a single probe within the resource constraints of NASA's New Frontiers Program. Achievement of this goal would require a small and focused set of science objectives.
The mission's science objectives, specified by the study science team, are divided into two groups: "Tier 1," essentially the science floor objectives that must be addressed to make the mission worthwhile, and "Tier 2," the next highest priority level, with objectives that prospective PIs could reasonably add, given sufficient resources. By request from the science team, this study used as requirements only the Tier 1 objectives:
-Determine the noble gas abundances and isotopic ratios of H, C, N, and O (and Ar?) in Saturn's atmosphere
-Determine the atmospheric structure at the probe descent location(s)
